The scientific committee organizing the event is made up of a scientist from: France, USA, Malaysia and Argentina.
Between August 14 -15, the first aquaculture, fisheries and marine biology international conference (ICAF 2023) will be held in London, United Kingdom, an opportunity in which a contribution from IFOP’s CREAN (Center for Harmful Algae Studies) has been accepted. (below attached summary translated into Spanish). This contribution has been prepared by six CREAN researchers, Oscar Espinoza, Pablo Salgado, Pamela Carbonell, Gemita Pizarro, Javier Paredes, and Leonardo Guzmán.
The presentation is on Monday between 14:20 – 14:40 (London time) which corresponds between 09:20 – 09:40 Chilean time. This conference is held through zoom platform, and shows how it is feasible to generate experiences exchanges using these technologies. The presentation is sent recorded, and presenter (in this case Dr. Guzmán) must be present electronically to answer questions.
On the occasion, a 15-minute presentation (5 minutes for questions) has been prepared, showing the progress that has been made in the last 10 years, with the incorporation of high-level training researchers, new technologies and tools to achieve a better understanding of the different noxious blooms that affect our country, particularly the national fjords.

Worldwide, marine proteins production has become more relevant for food security and nutrition. Chile is the world leader in fishing and aquaculture, ranking seventh for its production levels, with export returns during 2021 of US$ 7,038 million.
Fisheries and aquaculture present challenges linked to sustainable planning and adaptation to climatic change. Both also face challenges such as environment changes from pollution, habitat loss, El Niño and La Niña, and Harmful Algal Blooms (HABs). FAN events have been increasingly observed over the last 50 years, which is challenging given the limited abilities to predict and control them, to remove toxins from shellfish, and the lack of antidotes to counteract toxins effects. All this requires strengthening prevention measures, among which monitoring programs (PM) are a key tool to mitigate its effects.
A PM is a space-time systematic activity, which provides information on certain variables natural trends that are used as environmental change indicators and eventually, risk indicators, which can be used to protect public health and to minimize risks social, economic and environmental problems. For a PM, there are tools ranging from satellite images to molecular biology techniques, but all of them aim to detect, identify and quantify microalgae responsible for HAB and, of course, in the case of toxic microalgae, detect and quantify the toxins.
This contribution shows the programs executed by Fisheries Development Institute (IFOP) and technically supports Fisheries and Aquaculture Undersecretariat, which monitors an important part of the national coastline, including the fjords and channels of the south (36°‒55°S), combining traditional and emerging techniques, which make it possible to have long-term time series, improve early warnings, estimate flowering areas, and even predict certain blooms, and consequently improve public health protection and minimize the effects on productive activities .
